Navigation bar with drop downs

I'm creating a site in which the navigation bar is supposed to have a series of drop down menus.

I have a .jss file that a co-worker fluent with javascript came up with the add into my site.

He specifically pointed out which parts to copy and paste and where to paste them in the script.

However, when I try to do it it isn't functioning correctly, the srop downs do not appear.

Any suggestions?

I've attached the index.html file which includes the code for the drop down menu.

If you look at the coding you can see where my co-worker gave specific instructions where to copy and paste the code.

I also included the base_template.dwt file that I am using for the original site where I need to paste the code.
